12W LED Growing Lamp E27 Base 4 Bands Plant Growing Bulb for Plant Works Best with Seeds through Flowering, Indoor Garden Greenhouse, Hydroponics and Aquatic Systems

Features:

*BOOST PLANT GROWTH CYCLE: works best with leafy seeds through flowering,good to start for vegetable plants like tomatoes, lettuce, bell peppers,cucumbers,orchids.
*Professional Proportion,4 Bands instead of 3 Bands,12 LED bulbs5 Red(630nm ) +3 Deep Red(660nm)+3 Blue(450nm)+1 Green(530nm).Many studies indicate that even with blue light added to red LEDs, plant growth is still better under light supplemented with green(From Wikipedia).
*450nm Blue as supplemental light for seedlings and young plants,especially when "stretching"must be reduced or eliminated. 530nm Green as a tool for eliciting specific plant responses such as stomatal control, phototropism, photomorphogenic growth and environmental signaling. 630nm and 660nm Red region has high photosynthetic relative quantum yield for a range of plants.
*High Efficiency:12W with 12 LEDs (1W/LED) low power consumption,high luminous efficiency,helps when the plant need extra boost of light, or a few of sun, raining, snowing , dark indoor etc

4 Bands Mix
BEST FOR GERMINATION THROUGH FLOWERING
It produces the fastest germination and drives the best vegetative and flowering results among all of the spectra options.
In addition to the blue and red wavelengths, this spectrum contains a small amount of green which is beneficial for the quality assessment of plants.
This spectrum is recommended for use in growth chambers as well as controlled environment agriculture operations of any size.

4 Bands Mix
Red (630nm) 41%
Deep Red (660nm) 25%
Blue (450nm) 25%
Green (530nm) 9%

450nm Blue as supplemental light for seedlings and young plants,especially when "stretching" must be eliminated.
530nm Green as a tool for eliciting specific plant responses such as stomatal control, phototropism, photomorphogenic growth and environmental signaling.
630nm Red has high photosynthetic relative quantum yield for a range of plants.
660nm Deep Red exhibits the highest action on red-absorbing phytochrome regulated germination, flowering etc.
